SRAM Automatix 2 Speed Hub (Coaster Brake)

Focus on the ride, not your gear with SRAM's Automatix 2 Speed Hub. A centrifugal clutch in the hub automatically changes gears based on your speed, and a coaster brake takes care of the stopping so there's no shifter, no cables, and no nonsense. All you'll have to do is sit up and enjoy the ride!
